IMPROVEMENT IN PHOTOGRAPHIC CAMERAS.

Specification forming part of Letters Patent No. 130,800, dated August 27, 1872.

Specification describing certain Improvements in the Manufacture of Camera-Boxes, invented by MATHIAS FLAMMANG, of New York, county and State of New York.

My invention consists of mechanism by means of which a camera-box can be'adjusted upon its platform with greater facility than has heretofore been possible.

Great difficulties are generally encountered in the use of large camera-boxes, such as sticking and unequal movement, unless great force is applied, in which case the inertia ofthe parts carries them beyond the point desired; also, there is considerable lateral motion which renders it necessary to readjust the stand, 85c. My invention makes it very easy to manipulate and get it perfectly true and unvarying in its movement.

Figure l is a plan, showing platform and bottom of camera box. Fig. 2 is section through as at, Fig. l.

A is the platform, upon which and near each side are attached the ways or tracks B. Upon the tracks B the rollers 0 travel when the camera-box is moved forward or backward.

The rollers are attached to the bottom D of the camera-box. The track B is wedge or V- shaped, and the rollers C have a corresponding groove. They are so shaped, first, to prevent any lateral motion second, dust cannot accumulate upon the track and interfere with the proper working; third, there is a greater bearing-surface obtained, and consequently less wear of the parts.

I claim as my invention- The wedge or V-shaped track and rollers grooved to correspond therewith, in combination with a camera-box and its platform, substantially as set forth.
